Cell Burial Services
Cell burial deals with Japanese knotweed on site by sealing it safely underground. At Eco Control Solutions, we’ve delivered this method across a wide range of commercial and development sites. It’s fast, cost-effective, and ideal where future groundwork won’t disturb the area.

Why choose Eco Control Solutions for cell burial?

How does it work?
Site visit or
photo ID
We assess the site using images or by arranging a visit, confirming the presence and extent of the knotweed.
Treatment recommendation
You’ll receive a clear plan outlining the best removal method, herbicidal, excavation, burial or translocation, based on your needs.
Removal carried out
with precision
We deliver the chosen treatment using licensed methods, whether that’s excavation, spraying, or burial, while keeping the site safe, compliant and contained throughout.
Ongoing protection and
full documentation
Backed by a 10-year warranty and Optional Insurance Guarantee.
All documentation is issued for legal, lender or planning use, giving you long term peace of mind.
Site visit or photo identification
We assess the site either in person or via submitted images to confirm the presence of Japanese knotweed and understand the extent of spread.
Confirming suitability for burial
We’ll assess whether cell burial is appropriate for your site, considering timelines, ground conditions, and future land use. If suitable, we’ll propose a clear plan showing where and how the knotweed-affected soil will be buried and contained.
Safe burial and
sealing
Our team excavates the affected soil and reburies it in a geotextile-lined cell, sealed and marked at a safe depth. This keeps the material securely on site and prevents regrowth or future disruption.
Documentation and ongoing support
You’ll get clear records showing what’s been done and where the buried material is located. If needed, we can revisit the site to confirm containment or support any future land use plans.
Residential property
Japanese Knotweed Excavation and Removal in Residential Property
Our client was the owner of a residential property with very limited access to the rear of the house, which comprised of a decked terrace overlooking a long, narrow garden, which sat several feet lower than the house. There were two infestations of Japanese Knotweed present within the garden. The first was growing underneath and around a garden shed, the second was growing in a rockery that had previously been a pond. The client opted for a full excavation and removal, rather than a treatment solution, as they had plans to redesign the garden.
